This report is focused around Lost and Found data using the intakes and outcomes data received for 2019-2021. Its goal is to reflect everything we could learn about L&F from the available data, make sure the numbers we see make sense, and highlight things that would be useful to show but some/all data required for them are missing.
Date range: 2019-01-01 to 2021-11-30
Scroll down or use the table of contents on the left to navigate throughout the document. Most sections contain multiple tabs showing different facets of a data type. Most plots are interactive, meaning they include tooltips and allow hiding and showing parts and zooming in and out. If something went wrong, look for the house icon in the top right corner of each figure to reset.
This table covers all strays and RTHs. RTH rates shown below are the number of strays with RTO outcome out of all strays.
When we go over this, let’s make sure we calculate the rate the same way you do, so we would want to make sure what we see makes sense. If these numbers are right, they are higher than the HASS averages, which are at 30% RTH rate for dogs and 2% for cats, and have been stable since 2019.
Normally, we would then split these by RTH method between RTO in the field and in the shelter, but since this has not been documented at PetPoint this is left out.
| Species | Year | Strays | RTH_Count | RTH_Rate |
|---|---|---|---|---|
| Cat | 2019 | 1034 | 31 | 0.03 |
| Cat | 2020 | 500 | 18 | 0.04 |
| Cat | 2021 | 457 | 21 | 0.05 |
| Dog | 2019 | 1032 | 296 | 0.29 |
| Dog | 2020 | 795 | 296 | 0.37 |
| Dog | 2021 | 628 | 263 | 0.42 |
These three time series show the RTH rate per month, to show whether there were times with particularly high or low rates as well as the overall trajectory. These figures show only dogs information because there were only 8 RTH cats in 2021.
It seems like the rate has been constantly improving since 2019, jumping up with the beginning of the pandemic.
This section shows the number of stray intakes over time, as well as the breakdown of strays by field/shelter intake. This helps give us some context to the above pattern – at least part of the RTH improvement might have come from the lower intake volume.
Dog numbers are pretty steady, suggesting that the differences in RTH rates between months are not a result of differences in intake volume.
This helps us to understand where strays come from, which in this case seems exclusively animal control (as opposed to public drop offs).
The average difference in length of stay (in days) between strays with RTH outcomes and all other strays is shown in the table below – roughly 10 days for dogs and 8 for cats when looking at the average.
That means that every successful RTH saves 10 days of care on average at Rochester Animal Services, and field RTH would save an extra day or two on average for RTH from the shelter.
This could translate to pretty significant cost savings at scale – assuming a daily cost of care of 30$, if 100 more dogs were returned home in 2021, it would have saved Rochester Animal Services about $30,000 in costs of care. This is a fairly simple calculation, but it gets at the magnitude of the potential benefits.
| Species | Outcome | Count | Average_Length_Of_Stay |
|---|---|---|---|
| Cat | Other Outcomes | 1919 | 12.15 |
| Cat | RTO | 70 | 4.47 |
| Dog | Other Outcomes | 1599 | 12.70 |
| Dog | RTO | 855 | 2.07 |
The following maps show stray intake and RTH rate by Census tracts to highlight geographical patterns. The first and second tab are similar to previous metrics; the third tab, RTH Gap, shows the number of strays who were not returned home per census tract.
The data in this section includes stray animals for which found addresses were present. There were 4478 strays after removing TNR animals. About a 120 had their found location as the shelter’s address and so were removed from mapping. 30 more had no house number or intersection which makes precise geocoding impossible, leaving 4317 animals overall, of which 2409 were dogs and 1877 were cats (31 others).
This was probably the most complete location data we have seen across HASS shelters – very few animals had to be removed for lack of specific address. Well done.
After this filtering, the data below (number of strays, rate of RTH, RTH gap) is shown for 2409 dogs of which 1102 were RTH. The next section shows the same maps for the cats.
This is fairly uniform around town, with a few exceptions, which is less common.
This combines the other two tabs to highlight where most additional RTH potential exists - it shows the number of strays NOT returned to home in each area. As the RTH rate is fairly uniform, it looks roughly similar to the first map.

This is similar to the maps above, but for 1807 stray cats.
The map looks somewhat similar from far out, but a few different areas stand out.
Since cat RTH rate is pretty low across the city, it is also low throughout in this map.
This is very similar to the stray map because of the low RTH occurrence for cats.

This map shows different demographic information for the DC area. “Black” refers to the % of people who indicated their race as black or African American.
One example of using both the census data and shelter data is below – there is a very clear positive correlation between stray intakes (dogs+cats) and the % of people living under the 100% poverty line, such that there more animals coming in from areas with higher prevalence of poverty.
Other things we could show if we had the data for it:
Thanks for reading through, and we’re looking forward to talking through it and thinking about more ways to make this data useful for you.
